摘要

Nano nickel-zinc-indium ferrite (NZIFO) (Ni(0.58)Zn(0.42)In(x)Fe(2-x)O(4)) particles with varied quantities of indium (x=0, 0.1, 0.2) have been chemically synthesized through a reverse micelle reaction and investigated by X-ray diffraction, transmission electron microscopy and by magnetic and Mossbauer spectral studies. The dependence of Mossbauer parameters, viz, isomer shift, quadrupole splitting, linewidth and hyperfine magnetic field on In(3+) concentration have been discussed. Mossbauer results are also supported by magnetization data. With these interesting ferromagnetic properties indium substituted nano nickel-zinc ferrites have potential applications in magnetic storage data. The dependence of Mossbauer parameters on nano NZIFO particles at 5 K and 300 K has been studied. The values of Bloch exponent (alpha) are in well accordance with that reported for bulk materials.
